🛠️ What is Edge Caching?
Edge caching involves storing website data on multiple servers located closer to end-users. This approach minimizes latency and accelerates content delivery, enhancing user experience and site performance.
⭐ Why is Edge Caching Important in SEO?
Edge caching plays a crucial role in technical SEO by speeding up page load times, reducing server load, and increasing website reliability. Fast-loading sites are favored by both users and search engines, leading to better search rankings.
⚙️ How Does Edge Caching Work?
- A visitor requests a page from your website.
- The request is served by the nearest edge server where the data is cached.
- If the cached data is current, it's delivered to the user quickly.
- If not, the edge server fetches the latest data from the origin server and updates the cache.
📌 Examples of Edge Caching Usage
- E-commerce sites using CDN to enhance global reach.
- Streaming services deploying edge caching for faster video delivery.
- News websites ensuring seamless access to articles for international audiences.
